PMMA is one of the most versatile polymer materials in digital dental manufacturing. It is easy to process, available in a wide range of shades and transparencies, and suitable for applications ranging from temporary restorations to full dentures and occlusal splints.
In CAD/CAM workflows, industrially manufactured PMMA blanks can be processed efficiently using dental milling machines. Compared with harder materials such as zirconia or cobalt-chromium, PMMA places relatively low mechanical demands on the milling process and enables fast, predictable manufacturing.
This guide explains the properties of PMMA, how it compares with other dental milling materials and which factors are important when designing and milling PMMA restorations.
